It's not OO but you can roll your own. See: http://sleep.dashnine.org/manual/functions.html#3 http://sleep.dashnine.org/manual/functions.html#3 It does threading using a fork(&function) abstraction. You can pass an initial set of variables to share but otherwise it's shared nothing. The fork returns an I/O handle which you can use to communicate values back and forth (even serialized objects). You can also wait(fork(&function)) to get a return value when the thread finishes.
